IMPROVEMENT IN CARRIAGE SHAOKLE.

TO ALL WHOM IT MAY CONCERN Be it known that I, F. M. IVELLER, of Evanston, in the county of Cook, and State of Illinois, have invented a new and improved Carriage Shackle; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in whieh- Figure 1 represents the side view of the shackle.

Figure 2 represents the side view of the parts of the shackle.

Figure 3, the top view of the shackle; and

Figure 4, its section on the line M N.

The invention being an improved shackle for the purpose of attaching the pole or thills to the axle-tree of a wagon, carriage, buggy, ctc., its nature consists in the convenience of attaching the pole or thills to or detaching them from the axle-tree without the use of a bolt or pin.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The shackle consists of two parts, (fig. 1,) the body A, and the shaft or thill iron B. The body, whosc back a being securely attached by welding or riveting, or other suitable manner, to the clamp 0 usually employed to secure the wo'od to the iron of the axle-tree, has its anterior side surface D (fig. 2) concave, and has two sides orjaws, E E, one of which, E, may be made of one piece with the body A, while the other of the same form and size, being supplied with a transversegroove, F, to receive a corresponding bar or cleat, G, on the body, for the purpose of sustaining the draught, is secured in its place to the body by bolts or screws, easily removed for purposes of repair. Each one of the jaws has a circular disk, H, attached to it by rivets or screws, for the purpose of easily removing the same for repair or alteration, the centre of the disk being at the same time the centre of the concave surface D of the body A, the disk being of the size to leave a space between itself and the surface D large enough to receive the semi-lunar disks K K of the pole or thill-iron. The pole or thill-iron B terminates with a fiat circular disk, I, placed vertically, and having the two semi-lunar disks K K attached to its sides by rivets or screws, which semi-lunar disks have such a shape and are so placed upon the disk I that when the forward end of the pole or thill is dropped to the ground, or a little below the level upon which the carriage stands, the open space L of the semi-lunar disks can readily be passed over the circular disks II on the jaws of the'shackle, and the convex surface of the thill-disk I and semilunar disks K K brought in contact with the concave surface D of the body A, when, by raising the end of the pole or thill, the disks of the chill-iron will revolve around and upon the disksof the jaws of the shackle and secure the connection between the pole thills and the axle'tree.

What I claim as my invention, and desire to secure by Letters Patent, is-

The carriage shackle constructed and operating substantially as herein described and specified.
